IMPROVEMENT lN COTTON WING-SWEEPS.

Specification forming part of Letters Patent No. 217,597, dated July 15,1879 application filed May 123, 1879.

To all whom it may concern:

Be it known that I, CHARLES E. ESTES, of Columbus, in the county ofMuscogee and State of Georgia, have invented a new and usefulImprovement in Cotton Wing-Sweeps,

- of which the following is a specification.

Figure 1 is a vertical longitudinal section of my improved sweep, takenthrough the line a: m, Fig. 2. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved sweep forcultivating cotton, which shall be so constructed that the parts subjectto wear may be readily ground to keep them sharp, may be readilyreversed and exchanged when one edge becomes worn or notched, which maybe moved down to take up the wear, and may be replaced with new oneswhen worn out at small expense, and which will leave the ground leveland smooth.

The invention consists in an improved sweep formed by the combination ofthe standard provided with the narrow wings, the narrow slotted blades,and the narrow point with each other, the blades being clamped betweenthe win gs and point, as hereinafter fully described.

A represents the standard of the sweep, which is secured to the ordinaryplow-stock by a heel pin or bolt in the manner of a shovelplow.

Upon the side edges ofthe forward part of the standard A are formedwings a, which have holes formed through their outer parts to receivethe bolts, by which the wings or plates B are secured to them. Theblades or wings B are made in the shape of obliqueangled parallelogramsor rhomboids, as shown in Fig. 2, so that the soil may pass over themevenly, and may be left flat and smooth.

The inner ends of the blades B are inserted beneath the narrow point C,and are clamped between the said pointC and the standard A by tighteningup the bolt that secures the said point to the said standard. Thisconstruction allows the blades B and point C to be made thin, so thatthey can be readily ground and thus kept sharp.

The blades B are slotted transversely to receive the bolts, by whichthey are secured in place, so that they maybe moved down to take up thewear. With this construction the blades B can be readily exchanged whentheir lower edges or outer corners become worn, and the blades B andpoint C can be readily replaced with new ones when worn out.

By the substitution of a triangular-shaped blade for the obtuseangledparallelogram blades B, secured in the same manner and by the samebolts, the plow, without extra cost, except the cost of the triangularblades, is converted, toall intents and purposes, into a solid sweep forrolling the soil toward the cotton instead of flat culture.

Both operations are useful for the differentand bolted to the wings, sothat their forward ends will be clamped between the said wings and thepoint, substantially as shown and described.
